Because neutrons are uncharged, they are more penetrating than alpha radiation or beta radiation. In some cases they are more penetrating than gamma radiation, which is impeded in materials of high atomic number.

I did not know that neutrons could penetrate farther than gamma rays by their virtue of being neutral. Also never heard gamma rays be called y-rays. Wonder what the z-rays will be if we ever name any.

The "y" you're seeing on the table is actually γ, or lower-case gamma!
